Used Takahashi FC60, serial number 8. OTA only but is tapped for finder bracket. Optics pristine but there are some marks/scratches on the OTA (unruly guide scope bracket bolts). Writing on outside of lens cell:Fluorite apochromat, D=60mm, MC, f=500mm, doublet. Asking $500 OBO. Great pick-up-and-go telescope.
